Method for Communication Between First and Second Nodes in a Network

2. The method according to claim 1, wherein the network is a long-range wireless network affording low energy consumption based on LoRa technology, the protocol is the LoRaWAN protocol and the first node is a device suitable for communicating on a LoRa network using the LoRaWAN protocol, referred to as a LoRa endpoint, and the second node is a LoRa network server, or the first node is a LoRa network server and the second node is a LoRa endpoint.

3. The method according to claim 2, wherein the first node is a server and the second node is a LoRa endpoint functioning in class A according to the LoRaWAN protocol, when the second node has received a first segment comprising blocks in a set of blocks, at each reception of a segment the second node measures a time since the reception of said segment and, when said time is greater than a predefined maximum time without a frame having been transmitted to the first node, transmits a protocol frame representing a request for transmission of data to the first node in order to enable the first node of transmit a new segment.

4. The method according to claim 1, wherein if, following the transmission of each segment to the second node, the first node does not receive an acknowledgement of reception from the second node after a predefined time following the transmission of the last segment, the first node transmits to the second node a segment containing at least the block with the lowest rank, the error identification code and an identifier representing the number of the block that has the highest rank in said segment.

5. The method according to claim 1, wherein the verification information is included in a header of said segment, said header further comprising information representing a change of set of blocks a value of which is modified each time a new set of blocks is transmitted to the second node and/or information representing a request for acknowledgement of reception, making it possible to activate or not a reception acknowledgement mechanism, the first node awaiting an acknowledgement of reception for the set of blocks from the second node when said mechanism is activated.

6. The method according to claim 1, wherein the information representing at least one block not received by the second node is a series of bits, each bit in the series representing a block in the set of blocks, and, for each bit, a first value of said bit indicates a reception of the corresponding block and a second value of said bit indicates non-reception of the corresponding block.

7. The method according to claim 1, wherein the acknowledgement of reception comprises information for identifying to which set of blocks said acknowledgement of reception relates and/or information indicating if, when there is a verification of integrity of the blocks received using the error detection code, the second node has or has not detected an error.

8. A non-transitory storage medium, wherein said storage medium stores a computer program comprising instructions for the implementation, by a device, of the method according to any of claim 1, when said program is executed by a processor of said device.
